Face mask Type IIR (Box 50 units)

does not suffice

Plastic clip around the nose is not easy to bend, it always springs back. air flows past the mask instead of through it.

Since I can't delete my review praising them to heaven, here's a correction: I gave a review about mouth caps from a brand that I had previously used. So they were comfortable, sturdy and a good fit. With this box a string broke at the first mask, didn't even have it on my nose yet! Number two strings were good, but it turns out the nose clip was not very wide, not flexible enough and only after a lot of squeezing and kneading did my glasses stay on my nose. I don't have the biggest nose, an average one and the fabric was already against that. These caps are nice if you are at a reasonable distance and for very short use. If you have to travel by public transport, I think they are really below par. Also a pity: it is not very clear which side should go in. No user manual in the box. You find out when setting it up. But then you've already touched it too much! (Blue side in, lighter blue color out). I contacted customer service after checking that many caps release the strings when you pull on the packaging.
